Wind power absorption process assessment method

Abstract

The invention provides a wind power absorption process assessment method. The method comprises the steps that basic information of wind power generation is collected, and abnormal data in the basic information is removed, wherein the basic information of wind power generation comprises actual power of fan power generation and cabin wind speed; fan states are subjected to category classification; a theoretical power value of a fan is calculated, and wind curtailment electric quantities under different states are calculated through the theoretical power value and an actual power value; and the wind curtailment electric quantities under an out-field blocked state and the wind curtailment electric quantities under an in-field blocked state are sequenced respectively, the maximum wind curtailment electric quantity in each group of states is found out, and main influence factors of wind power absorption are determined according to the maximum wind curtailment electric quantities. Through the method, the wind curtailment electric quantities caused by different reasons in the wind power absorption process can be assessed accurately, and the main factors influencing the wind curtailment electric quantities can be found out, so that the method is beneficial for taking accurate wind power absorption countermeasures.

Description

technical field [0001] The invention relates to an evaluation method, in particular to an evaluation method for wind power accommodation process. Background technique [0002] With the depletion of fossil energy and the increasing social attention to the ecological environment, wind power has attracted more and more attention from people, and the application of wind power has become more and more extensive. Taking my country as an example: by the end of 2015, the installed capacity of wind power in the country Reached 129 million kilowatts, especially in some provinces, the proportion of wind power installed capacity has exceeded 40%. [0003] However, while the application of wind power is developing by leaps and bounds, the problem of wind power consumption is becoming more and more serious. In 2015, the abandoned wind power in my country alone reached 34 billion kWh, with an average wind power abandonment rate of 15%. Therefore, how to solve the problem of wind power consu...

[0003] However, while the application of wind power is developing by leaps and bounds, the problem of wind power consumption is becoming more and more serious. In 2015, the abandoned wind power in my country alone reached 34 billion kWh, with an average wind power abandonment rate of 15%. Therefore, how to solve the problem of wind power consumption It has become a technical problem in the field of wind power. In the prior art, the analysis of the influencing factors of the wind power accommodation process includes the forecast curve method, the plan curve method, the model machine method and the power curve method. However, it is difficult for the above-mentioned various methods to Accurately assess the influencing factors of abandoned wind power in the process of wind power consumption, and then cannot make accurate countermeasures
